Some basic questions (they may sound obvious, but they are important :p ):
- Are you building the package in guvnor? (click on the package name and click on "Build Package" button).
- Are you accesing kbase.getProcesses() AFTER the agent builds it?
- Are you checking for errors in the agent? (The first place to look at it the console log. Then you can use an KnowledgeAgentEventListener)
